THERMOMETER.

To all whom t may concern.'

Be it known that I, LAWRENCE E. PARLI- MAN, a citizen of the UnitedStates, residing at Sea Cliff, Long Island, in the county of Nassau andState of New York, have invented new and useful Improvements inThermometers, of which the following is a specification.

This invention relates to thermometers and has for its object to providea simple, cheap and highly etiicient device of this kind, whereby thetemperature of the outside atmosphere may be determined as well as thatof the inside.

To these ends the invention consists in the novel details ofconstruction and combination of parts more fully hereinafter describedand particularly pointed out in the claim.

Referring to the accompanying drawings forming a part of thisspecification in which like numerals designate like parts in all theviews Figure l is a front elevational view of my improved device, andFig. 2 is a longitudinal sectional. view thereof showing the deviceattached to a wall.

' of temperature.`

My improved thermometer comprises a base 1 on each end of which issecured the fastening lug?J for securing the thermometer to a wall orpartition 3, on the inside of a room or building. Held to the front ofthe base and spaced an equal distance apart by two stays 4L and 5, aretwo thermometer tubes 6 and 7 between which is the usual scale 8 fordetermining the different degrees The tube 6 is of the usual form asemployed on the ordinary thermom eter now in use, but the tube 7 is bentat right angles at its lower end to form a horizontal extension 9 whichis adapted to project through a hole 10 in the wall or partition 3 intothe outside atmosphere, and is provided on, its outer end with the usualbulb 11. After the thermometer has been placed in position on a wall asshown in Fig. 2, the hole 10, around the tube, is plugged with anysuitable material 12 and closed at Specification of Letters Patent.

its outer end with a bushing 13, which bushing is split to allow of itbeing secured in place. The bushing is held in position by means of thescrews 111, which screws also hold a small screen or basket l5, adaptedto incase the bulb 11 and protect the same against injury.

.F rom the foregoing it may be noted that by the employment of a deviceconstructed in accordance with my invention, the temperatures of boththe inside and outside atmosphere may be determined at a glance and thatthe manner now in vogue of hanging a thermometer outside of a window,may be eliminated. The device may be placed in any convenient place in aroom or building but may be more readily applied to the Window sash,

It is obvious that those skilled in the art may vary the details ofconstruction and arrangements of parts without departing from the spiritof my invention and therefore I do not wish to be limited to suchfeatures except as may be required by the claim.

Vhat is claimed as new is:

A thermometer comprising a base adapted to be fastened to the insidewall of a room and provided with a graduated scale, a tube mounted onthe base and arranged for coperating with the scale to indicate thetelnperature of the room, a second tube having its bulb portionextending through the wall and into the external atmosphere, packingaround the tube within the house-wall, a bushing forming a plug toretain the packing and tube, a basket fitted over the outside bulb andforming a guard therefor, and means securing thel basket and bushing tothe outside wall, substantially as described.

In testimony whereof I 'aiiix my signature in presence of two witnesses.
